Material/ PVD & CVD Coating Compatibility Table

* Can be coated after it has been Chrome plated

Please Note:

1. This is only a sample listing of materials and should not be considered definitive. Information has been generalized – please contact a Richter Precision Inc. representative regarding your specific application.
2. All parts, regardless of coating process, should be sent to us already heat treated to your required hardness. In the case of the CVD and TD processes, parts will be annealed during coating and then re-heat treated afterward. However, being hardened prior to coating will reduce stresses and distortion during coating.
3. When considering the PVD process, whenever appropriate for the material, we recommend that final draws be at least 800° F: this will ensure that no annealing and/or distortion occur.
